"Although Cody did a great job on my roof, he then stole $9600.00 from my parents after I referred him to them. He has also stolen money from several other customers over the last year. My parents have been unable to get their money back from him to date. He has also been known to change his business name when customers realize he is taken their money without doing the work. He is a con and his felonious business practices should make anyone leery of hiring him. "

Customers say: Quick response

"Our basement needed to be remodeled which included a bedroom with bath and pantry. I reached out to Aubrey and Son because, Beau, the owner, and crew, did a fantastic job on phase one (our decks fencing and stairs). I needed the job completed within a certain time frame, within my budget, and some help with design. I already knew from phase one, that the employees were always timely and polite, and they did a great job with the phase one project. Well, they did it again !! We are very happy and will reach out again on the 3rd and final phase in the near future. Thank-you to Beau and his crew for a job well done. We appreciate you."

"I have owned my construction company in the Seacoast for 40 years and Tim is by far one of the more accomplished carpenters I have come across. He does first quality work with framing to finish work and has done custom cabinets for me that I could not be happier with. He is very reliable and always shows up on time and his cost are very competitive with the industry standards."

"We had Tim and his team work on a full re-model In Greenland, NH. This was a full gut job as the house needed major repairs and updates. What we got in return was a beautiful 3 bedroom 2 bath condo on one side and a 1 bedroom and 1 bath on the other side! Tim and his team are wonderful to work with, he listened to our ideas and helped us make them come to! We are so happy with the finished product and working with Tim that we are going to use him and his team on our next project!"

FAQs for addition to existing structure building service projects in Portsmouth, NH

You can typically raise your roof by four to eight feet, depending on your home's structure and roof design. The exact amount depends on factors like roof slope and framing support. Raising the roof creates additional interior space, enhances natural light, and increases your home's value. Consult a professional to determine the feasible height increase for your home.

Yes, you need a building permit to raise your roof. Obtaining a building permit ensures your project complies with local building codes and safety regulations. A professional contractor can assist with the permit and inspection process and ensure all legal and safety requirements are met. Your contractor will be familiar with building codes in your area, which can differ between cities or states.

While it's possible to raise a flat roof, it requires extensive structural modifications. Flat roofs lack the attic space and support structures of pitched roofs, so raising them involves significant engineering to ensure safety and durability. This process can be complex and costly, so professional assessment is essential before undertaking a project of this magnitude.
